Gill FitzHugh of Fairfax shot even-par 71 on his home Army Navy Country Club course yesterday, finished with a 54-hole total of 3-under-par 210 and coasted to victory by eight strokes in the Northern Virginia Amateur.

It was FitzHugh's fourth Northern Virginia victory and third in the last four years. He held a five-shot margin after a second-round 67 and was not challenged in the final round.

Neff McClary, a two-time winner of this event, was the only one with a remote chance of catching FitzHugh, but after FitzHugh shot a par 35 on the front nine, McClary, a former Virginia state champion, had fallen from five shots back to eight behind.

Chuck Tickle of Chantilly (74 yesterday), who moved here last year from Pulaski, Va., and Peter Jacobi of Army Navy (76), the first-round leader, tied for third at 223. Rod Stanley of Chantilly (77) and Bob Harwick of Westwood (72) were next at 225.

"I know it sounds weird, but I never felt confident until I got the 16th hole out of the way," said FitzHugh, who made par on that tree-lined par 5.

"I was probably more nervous starting out today with a five-stroke lead than I was starting out last year, one shot behind the leader. I just kept thinking about the time Billy Casper made up seven shots in nine holes on Arnold Palmer {to win the 1966 U.S. Open}. Neff's a tough player.

"I played real well and hit a lot of greens. My plan was to make par on every hole," added FitzHugh, who also was the tournament host.
